To all whom it may concern:

Be it known that I, Ivan L. PETERSON, a citizen of the United States, residing at Burlingame, in the county of San Mateo, State of California, have invented a new and useful Loom, of which the following is a specification.

My invention relates to improvements in looms and consists of means whereby the quantity of fabric woven in a given time or the output exceeds that woven in a loom of 'a similar character but provided with a vibrating frame carrying a reed and a shuttle race of the ordinary type.

My present novel invention is not merely an attemptto increase the speed of the shuttle, nor the speed of the reed or shuttle lay, but broadly relates to novel means for increasing the loom speed by reducing the breaking of the threads; the time necessary for re-tying same, and by an arrangement to permit the shuttle to move on 'a stationary plane instead of a vibrating plane carryii'ig the shuttle lay and the reed.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Figure 1 is a side elevation of a portion of a loom having applied thereto certain parts of my invention. Fig. 2 is a perspective view of certain detached portions of the tie vice, on an enlarged scale. Fig. 3 is a vertical section of certain detached'portions of the device. Figs. 4 and o are lan views of certain of the parts seen 1n Fig. 3. Fig. 6

is a front elevation of the parts seen in Fig. 5.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :-1 designates the frame of a loom in which is journaled the driving shaft 2 to which motion may be imparted in any well known manner. The shaft 2 has fast thereon a gear wheel 3 thatis in mesh with'a gear wheel 4 journaled in the frame 1. The shaft 2 is provided with crank arms 5 to which is coupled one extremity of a link (5 whose opposite end is coupled to a crank arm or its equivalent 7, so as to impart a rocking motion thereto, and consequently to the rock shaft 8 journaled in the frame 1. The shaft 8 has fast thereon a cylinder, or its equivalent 9, provided with teeth 10 forming a comb or open reed 11 which moves in unison with said rock shaft 8. The frame 1 has secured thereto a face-bar or breast-beam 12, over which passes the fabric 13. In order to properly control the lay of the fabric 13 upon the facc-bar 12, there is a plate 14 lying on the fabric 13, its width being such as to lie close to the line of the fabric where the last thread from shuttle 15 is placed by the comb or open iced 11 and its action is such that it holds the fabric 13 tightly and closely during all periods except. such small portion of time as the comb or open reed it is forcing the fabric 13 outward by the thickness of the last weave-thread distance. During the momentary period, the plate 11 is lifted by mechanismhereinafter described. The comb or open reed may be removable from the rock-shaft 8, said comb being secured thereto by suitable fastenings 16' at suitable intervals.

In the regular or ordinary loom, the travel of the vibrating frame at the point of the reed is, perhaps, ten inches in each direction or twenty inches to make one cycle. A loom that is weaving a fabric of say sixty shuttle threads to the inch of length will therefore involve the rubbing ettect of the reed bars on each thread of twelve hundred inches or one hundred feet while weaving the one inch of fabric and the mean length of five inches being assumed as the distance each thread is held in the reed during its action, means that each thread is subjected to the vibrating or rubbing effect of six thousand inches or five hundred feet while weaving the five inches of fabric. The finer the texture of the fabric. the greater is the rubbing distance.

The rock-shaft 8 with its comb or open reed 11 may be arranged to afford a travel distance in contact with threads of about one tenth of the distance required by the vibrat ing reed, and the rubbing distance is therefore but one tenth in its range of the ordinary methods under same conditions of fabric. The saving to be accomplished by this improvement is in the reduction of time required for the tying of threads which are weakened and broken by the rubbing effect of the reed bars, and while the machine may not necessarily be driven faster, that is, that the shuttle 15 may be thrown across the weave at any greater number of'casts each minute, the saving of weaving time accenplished more than off-sets even some small reduction of shuttle-speed. This is also a point for consideration, as the present high velocity of the shuttle is in its action very severe on shuttle-bobbin-thread or weavethread and much stoppage of loom may be charged to broken weave-thread.

It is evident that, with this improvement, there will be a material saving in labor with the same output, or an increased output of material with the same labor from fifteen to twenty-five per cent. as compared with the ordinary loom in use at present.

The reed bars 17 are of usual construction and are supported in the shuttle or race way 18 which latter is rigidly secured in the frame 1 of the loom. The frame 1 is provided with brackets 19 in which are journaled, as at- 37, the arms or levers 20 whose free ends are provided with fingers 41 that are adapted to act upon the weft yarn or filling, as hereinafter described. The levers 20 are provided with lugs 44 that cooperate with cams 42 fast on the shaft 38 as will be understood from Figs. 3 and 4, for a purpose hereinafter described. The levers 20 are retained normally, in the positions seen in Fig. 5 by springs 43. The plate 14 is provided with depending members or guide bars 27 that slide in ways 28 for a purpose hereinafter described, it being noted that said bars 27 are retained in position in the frame 1 by plates 25) that are held in position by bolts 30. The lower extremities of the guide bars 27 rest upon cams 84, one of which is seen in Figs. 3 and 4,-said cams being fast on the shaft 25 that is journaled in bearings 24 that project'from the angle bar 23 secured in the frame 1. The shaft 25 has fast thereon one end of alever whose opposite end rests upon a cam 36 that cooperates there with, it being understood that said cam 36 is fast on the shaft. 2. The harness roll 22 is journaled in bearings 21, as will be understood from Fig. 3.

45 and 46 designate the cloth and the warp beams, respectively. which may be operated in any well known manner.

The operation is as follows:The shuttle 15 after passing through the shed formed by the warp yarn 31 is brought into the position seen in full lines in the right hand portion of Fig. 5. This will cause the weft or filling carried by said shuttle 15 to lie in the position indicated at a in said Fig. 5. At the instant the shuttle 15 has passed the reseen in full lines in said Fig. 3 and also in Fig. 5 and thus beats the weft or filling into the fabric 13. thereon are then returned to their normal position by the tension of the spring 43, while the cam 42 is returning into its normal position seen-in Fig. The shuttle 15 is The lever 20 and finger 41' then shot through the shed from its position of Fig. 5 into that seen in dotted lines in the left hand portion of said figure. The

shnttle15 in moving from right to left causes the weft or filling carried thereby to lie in the position indicated at 6 after which the lever 20 and finger 41 are moved in the direction indicated by the arrow f and said and causes said filling to lie in the position indicated at it by reason of the contact of said finger with the filling or weft yarn. The teeth 10 are then brought from their position, indicated in dotted lines in. Fig. 3. into that seen in full lines in said figureand beat up the weftor filling into the'fabric 13. The cam 42 is then returned to its normal position seen in Figs. 3, 4 and whereupon the levers 20 are also returned to their normal positions by the tension of the springs 43. Simultaneously with the heat ing up of the weft or filling into the fabric 13 the cam 34 elevates the bars 27: and consequently the plate 14 secured thereto so as to remove the latter from its contact with the fabric 13 as will be understood from Fig. When the plate 14 is in its elevated .position the fabric 13 is drawn in the direction indicated by the arrow m by the cloth v beam 43 to the extent of one weave thread. Motion is imparted to the cam 34 through the rock shaft and lever by the rotary motion of the cam 36. Vhen the fabric 13 has been drawn in the direction indicated by the arrow m, and to the desired extent,the plate 14 is lowered and bears upon the fabric 13'so as to retain the latter firmly in,

position on the angle bar 23, after which the operation hereinbefore described is re peated. I
